Magnetic components using soft core materials are widely used in power electronic converters. The hysteresis effect of the material leads to power loss and harmonic distortion. If this effect can be modeled in system-level time-domain simulation, the performance of the magnetic component in combination with power converters can be predicted more accurately during the design phase. This work proposes an approach to model the hysteresis effect of soft magnetic materials in magnetic circuits based on the permeance-capacitance analogy.

“…4. The core loss density for Philips 3C8 ferrite at 100°C can be represented by (9) This error can be attributed to two main facts: 1) the sample-to-sample variation in the properties of the material, which can be as high as up to 530% [2], and 2) the different characteristics of the measurement systems employed. According to Philips, the accuracy of its model is k25% and that of its measurement system, relative to a calorimetric measurement, is 3 5 % for MnZn ferrites [7].…”

“…Several attempts [ 1,2,3,4,5] have been made to establish a reliable method suitable for core loss measurement at high frequencies. In such measurements, the major challenge is to minimize amplitude and phase errors introduced by parasitic effects in the circuit, by time delays in the coaxial cables and oscilloscope, and by the digitizing process.…”

This paper describes an automated measurement system for core loss characterization in high frequency magnetic components. This system can accomplish these aims, within specified magnetic induction and frequency ranges, and at different temperatures, with high accuracy, due to the techniques used in the acquisition and computation of the waveforms involved in loss calculation. The core loss characterization, obtained by fitting the core loss density (per unit volume) versus frequency and magnetic induction, permits the use of an equation, which is a very useful tool for the design optimization of high frequency magnetic components, such as transformers and inductors for switched mode power supplies.

Abstract-A new integrated magnetic full wave dc/dc converter 1 that provides flexible transformer design by incorporating an independent output inductor winding is introduced. The transformer is implemented on a traditional three-leg magnetic core. The inductor winding can be separately designed to control the output current ripple. The cross-sectional area of the inductor core leg can be reduced dramatically. The operation and performance of the proposed circuit are verified on a 100 W prototype converter.Index Terms-Current doubler, dc-dc converter, full wave topology, integrated magnetics.
